Cisco OTV

Browse Source 
Implements the CISCO-OTV-MIB to retrieve OTV counters from Cisco devices.
This collects information on the configured Overlays and Adjacencies

Statistics are collected for the amount of VLAN's on each overlay and the amount of MAC addresses available over each OTV endpoint.
OTV alerts are collected and generated if the appropriate alerting rules exist.

Data is displayed under routing at both the global and device level.

Includes function snmpwalk_array_num, which performs a numeric SNMPWalk and returns an array containing $count indexes
One Index:
 From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
 To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27.18']['655360'] = 0
Two Indexes:
 From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
 To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27']['18']['655360'] = 0
And so on...
